Chloride resistance of concrete containing nanoparticle ...

To improve the chloride resistance of traditional polymer-modified cementitious (PMC) coating, a novel nano-PMC coating was synthesized through incorporation of nano-SiO 2 or nano-TiO 2 suspensions into acrylic emulsion. Water absorption ratios, Coulomb electric fluxes, and chloride diffusion coefficients of coated concrete at different ages were tested.
